Introduction: Biomedical technology holds the promise of extending human life spans; however, little research has explored attitudes toward life extension. Methods: This survey asked young adults (n = 593), younger-old adults (n = 272), and older-old adults (n = 46) whether they would take a hypothetical life extension treatment as well as the youngest and oldest age at which they would wish to live forever. Results: Age cohorts did not vary in their willingness to use life extension; however, in all three age cohorts, a plurality indicated that they would not use it. Men indicated a higher level of willingness to use the life extension treatment than women. Younger-old and older-old adults indicated that they would prefer to live permanently at an older age than younger adults. Discussion: If a life extension treatment were to become available that effectively stopped aging, young adults may be likely to use such a treatment to avoid reaching the ages at which older cohorts say they would prefer to live forever.

简介：生物医学技术有望延长人类寿命；然而，很少有研究探讨延长寿命的态度。方法：本次调查询问了年轻人（n  = 593）、年轻的老年人（n  = 272）和老年人（n = 46）他们是否会接受假设的生命延长治疗以及他们希望永远活下去的最年轻和最年长的年龄。结果：年龄组在使用延长寿命的意愿方面没有变化；然而，在所有三个年龄组中，多数人表示他们不会使用它。男性表示比女性更愿意使用延长寿命治疗。较年轻和较年长的成年人表示，他们更愿意比年轻人更长寿。讨论：如果有一种有效地阻止衰老的延长寿命治疗方法可用，年轻人可能会使用这种治疗方法来避免达到老年群体所说的他们更愿意永远活下去的年龄。
